SSH brute force connection attempts #fail

Collected these over the past few months, reverse chronological order. Seeing different machines attempting to connect hundreds of times a day each is just, wow.

Some might say that a SSH blacklist daemon might help, but it only increases the time taken for a brute force attempt, and is of no use against a botnet trying to brute force the ssh login.

There are plenty of things that can be done to lock down the ssh server, and restricting it to only publickey is by far one of the most effective, counting that the resource (the server) you’re protecting is pretty important.
Plenty of interesting IPs/hosts in this list, take a look if you’re really interested, heh. 😉
